 901  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
 902  * stack that meets the minimum architecture alignment requirements for DMA.
 903  * Such a buffer is useful for DMA operations where flushing and invalidating
 904  * the cache before and after a read and/or write operation is required for
 905  * correct operations.
 906  *
 907  * When called the macro creates an array on the stack that is sized such
 908  * that:
 909  *
 910  * 1) The beginning of the array can be advanced enough to be aligned.
 911  *
 912  * 2) The size of the aligned portion of the array is a multiple of the minimum
 913  *    architecture alignment required for DMA.
 914  *
 915  * 3) The aligned portion contains enough space for the original number of
 916  *    elements requested.
 917  *
 918  * The macro then creates a pointer to the aligned portion of this array and
 919  * assigns to the pointer the address of the first element in the aligned
 920  * portion of the array.
 921  *
 922  * Calling the macro as:
 923  *
 924  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
 925  *
 926  * Will result in something similar to saying:
 927  *
 928  *     uint32_t    buffer[1024];
 929  *
 930  * The following differences exist:
 931  *
 932  * 1) The resulting buffer is guaranteed to be aligned to the value of
 933  *    ARCH_DMA_MINALIGN.
 934  *
 935  * 2) The buffer variable created by the macro is a pointer to the specified
 936  *    type, and NOT an array of the specified type.  This can be very important
 937  *    if you want the address of the buffer, which you probably do, to pass it
 938  *    to the DMA hardware.  The value of &buffer is different in the two cases.
 939  *    In the macro case it will be the address of the pointer, not the address
 940  *    of the space reserved for the buffer.  However, in the second case it
 941  *    would be the address of the buffer.  So if you are replacing hard coded
 942  *    stack buffers with this macro you need to make sure you remove the & from
 943  *    the locations where you are taking the address of the buffer.
 944  *
 945  * Note that the size parameter is the number of array elements to allocate,
 946  * not the number of bytes.
 947  *
 948  * This macro can not be used outside of function scope, or for the creation
 949  * of a function scoped static buffer.  It can not be used to create a cache
 950  * line aligned global buffer.
